A randomized controlled trial of electromagnetic therapy in the primary care management of venous leg ulceration

OBJECTIVE: The aim was to establish the potential efficacy, tolerabilityand side-effect profile of electromagnetic therapy as an adjunctto conventional dressings in the treatment of venous leg ulcers. METHOD: A prospective, randomized, double blind controlled clinicaltrial was carried out in a dedicated leg ulcer clinic basedin one urban general practice. Nineteen patients with leg ulcersof confirmed venous aetiology were assessed. The main outcomemeasures were rate and scale of venous leg ulcer healing, changesin patient-reported pain levels, quality of life, degree ofmobility, side effect profile and acceptability to patientsand staff. RESULTS: Sixty-eight per cent of patients attending this dedicated clinicachieved improvements in the size of their ulcer (4, 21%, healedfully) and in reduced pain levels (P < 0.05) during the trial,despite the chronicity of ulcer histories. Patients treatedwith electromagnetic therapy at 800 Hz were found at day 50to have significantly greater healing (P < 0.05) and paincontrol (P < 0.05) than placebo therapy or treatment with600 Hz. All patients reported improved mobility at the end ofthe study. The electromagnetic therapy was well tolerated bypatients, with no differences between groups in reporting adverseevents, and proved acceptable to staff. CONCLUSION: Despite the small numbers in this pilot study, electromagnetictherapy provided significant gains in the healing of venousleg ulcers and reduction in pain. Keywords.

Effects of instruction by practice assistants on inhaler technique and respiratory symptoms of patients. A controlled randomized videotaped intervention study

BACKGROUND: Many patients with asthma or chronic obstructive pulmonary diseaseuse their medication inhalers incorrectly. General practitioners,pharmacists and other health care providers do not always havethe opportunity to instruct patients in correct inhaler technique. OBJECTIVE: To find out whether the inhaler technique and respiratory symptomsof patients can be improved after instruction by practice assistants. METHODS: Single blind, randomized intervention study in which 48 patientswho had been using a dry powder inhaler for at least one monthtook part. Their inhaler technique was videotaped on two visitswith a two-week interval between visits. The inhaler techniqueon the videos was subsequently scored by two experts on ninecriteria. At both visits the patients completed a questionnaireabout their respiratory symptoms. After the first video, 25patients were randomly chosen to receive instruction from oneof six practice assistants who had followed a one evening courseabout inhaler instruction, and who had been issued an instruction-set. RESULTS: The patients who received instruction had a significantly greaterreduction in number of mistakes at the second visit than thepatients who did not (P = 0.01). The instructed patients alsoreported less dyspnoea at the second visit (P = 0.03). No effectof instruction was found on wheezing, cough and sputum production. CONCLUSION: The inhaler technique of patients can be improved significantlyby the instruction of patients by trained practice assistants,possibly resulting in less dyspnoea. Keywords.

Direct observation of nutrition counseling in community family practice

BACKGROUND: Despite the large potential of dietary changes to reduce morbidity and mortality, the frequency, time spent, and factors associated with nutrition counseling in primary care are not well studied. METHODS: In a cross-sectional study of 84 family physician practices in northeast Ohio, nutrition counseling was measured by direct observation on 2 days for all consecutive ambulatory visits. The frequency, time spent, and patient and visit characteristics associated with nutrition counseling were determined. RESULTS: Among 138 family physicians, only 6% included nutrition counseling in the majority (>50%) of patient encounters. Among 3475 consecutive outpatient visits in adults, nutrition counseling occurred in 24% of all patient visits, 17% of visits for acute illnesses, 30% of chronic illness visits, and 41% of well-care visits. The average time spent on nutrition counseling was 55 seconds, ranging from <20 seconds to >6 minutes. Nutrition counseling occurred in 45% of visits for diabetes, 25% of visits for cardiovascular disease, 31% of visits for hypertension, 26% of prenatal visits, and 33% of visits by obese patients (body mass index >30). Nutrition counseling was more likely to occur during visits by patients who were older or had diabetes mellitus, during visits for well care or chronic illness, and during longer visits. CONCLUSION: Despite considerable variability from physician to physician, nutrition counseling occurs in approximately one fourth of all office visits to family physicians. The observed efforts by family physicians to focus nutrition counseling on high-risk patients may increase its impact.     

Prevention in practice: results of a 2-year follow-up of routine health promotion interventions in general practice

BACKGROUND.: The effectiveness of health promotion activity in general practiceon risk factor reduction for coronary heart disease remainsthe subject of active debate. OBJECTIVE.: The study aimed to assess the impact of practice-based healthcheck-ups on health behaviours over a 2-year period. METHOD.: A general practice cohort of 7123 patients from 18 practiceswas surveyed. Eight hundred and forty (12%) patients had beenoffered a heafth check within a 12-month period from September1992 and 621 (9%) received one. Two hundred and fifty patients(40%) were asked back for follow-up after their health check. RESULTS.: Over a 2-year period there was no difference in smoking cessation,alcohol consumption, weight loss nor the amount of exercisetaken between those who attended for a health check and thosewho did not. The food score chosen to assess dietary change(Oxcheck) showed a statistically significant 1.16-point risefor the whole sample over the survey period. There was a significantdifference in mean food score change between heafth check attendersand non-attenders (Mann-Whitney U test: P << 0.002). Maintenanceof dietary improvement over a 2-year period was not affectedby health check attendance. CONCLUSIONS.: This study confirms the low impact of health checks on the selfreported modification of cardiovascular risk factors and showsthat maintenance of appropriate health behaviour change is nomore likely in those who have received a health check.

Colorectal cancer and polyps in patients aged 40 years and over who consult a GP with rectal bleeding

BACKGROUND: Rectal bleeding is common in the community and in general practice,but few studies have examined the causes of rectal bleedingin patients presenting to general practitioners. OBJECTIVE: To determine the frequency of neoplastic conditions in patientswith rectal bleeding presenting in general practice and to explainthe associations between presenting symptoms and final diagnoses. METHODS: We conducted two studies, the first in 1989, the second in 1991,in which we invited Danish general practitioners to register3–4 patients aged 40 and over presenting with rectal bleeding. RESULTS: In Study 1 among 208 patients aged 40 and over and presentingwith a first episode of rectal bleeding, colorectal cancer andpolyps were present in 15.4 and 7.7%, respectively. In Study2 among 209 patients aged 40 and over and presenting with overtrectal bleeding, 156 reported a first bleeding episode or achange in their usual bleeding pattern, and in this group colorectalcancer and polyps were diagnosed in 14.1 and 11.5%, respectively.In the group with unchanged bleeding the cancer polyp prevalencewas 6.7% (P < 0.05). The patients in both studies were followedthrough a yearly letter to the GP for at least 32 and 22 months,respectively. CONCLUSIONS: A joint analysis of the two study populations showed that onlyage and change in bowel habit contributed to differentiatingthe cancer from the non-cancer patients. Keywords. Colorectal cancer, polyps, rectal bleeding.     

National Ambulatory Medical Care Survey: 2004 summary

OBJECTIVES: This report describes ambulatory care visits made to physician offices in the United States. Statistics are presented on selected characteristics of the physician's practice, the patient, and the visit. Selected trends in office visits are also presented. METHODS: The data presented in this report were collected in the 2004 National Ambulatory Medical Care Survey (NAMCS), a national probability sample survey of visits to office-based physicians in the United States. Sample data are weighted to produce annual national estimates using an estimator that uses a revised nonresponse adjustment. RESULTS: During 2004, an estimated 910.9 million visits were made to physician offices in the United States, an overall rate of 315.9 visits per 100 persons. Overall, 58.9 percent of visits were to physicians in the specialties of general and family practice, internal medicine, pediatrics, and obstetrics and gynecology. In 2004, primary care specialists provided 87.2 percent of all preventive care visits. The percentage of visits relying on Medicaid or the State Children's Health Insurance Program increased by 36% between 2001 and 2004. Essential hypertension, malignant neoplasms, acute upper respiratory infection, and diabetes mellitus were the leading illness-related primary diagnoses. There were an estimated 105.3 million injury-related visits in 2004, or 36.5 visits per 100 persons. Diagnostic or screening services were ordered or provided at 85.9 percent of visits, and counseling, education, therapeutic, or preventative services were ordered or provided at 42.0 percent of visits. Medications were prescribed or provided at 64.2 percent of visits.     

Effect of Helicobactor pylori eradication therapy on dyspeptic symptoms in primary care

OBJECTIVE: The aim was to explore the effect of eradication therapy ondyspeptic symptoms in patients with known peptic ulcer disease(PUD). METHOD: A total of 164 known dyspeptics and 147 non-dyspeptic attendersat six UK general practices were recruited. The Helisal RapidBlood test was performed in the practices and eradication therapyleft to the preference of the general practitioner. Patientswere followed prospectively by a Likert scaled symptom questionnaireand record review. The symptom questionnaire distinguished betweenpatients known to have dyspepsia and those not. RESULTS: There was a statistically significant decrease in dyspepticsymptoms in patients with known PUD who received eradicationtherapy (n = 43, Z = –2.63, P = 0.009). CONCLUSIONS: Eradication of Helicobacter pylori in primary care can leadto a reduction in consumption of H2 receptor antagonists andhence cost savings. This study demonstrates that dyspeptic symptomsalso decrease. The questionnaire could be used in further studiesto evaluate the effect of management on dyspeptic symptoms inthe primary care setting.

Local clinical guidelines: description and evaluation of a participative method for their development and implementation

BACKGROUND: National guidelines are rarely followed by immediate changein clinical behaviour. We present our experience of an activeeducational method for local development and implementationof a guideline. OBJECTIVE: To evaluate the effectiveness of a participative method fordeveloping local clinical guidelines. METHODS: A trial in a district of the effect of guideline developmentincorporating active participation of intended recipients onsubsequent relevant prescribing. It was carried out in WirralFamily Health Services Authority district (the Wirral peninsula)comprising 69 general practices covering a population of 345763. An exemplar guideline on ‘hypertension in the elderly’was developed by the method described. The principal recommendeddrug was bendrofluazide 2.5 mg once daily. The differences inprescribed daily doses (PDD) of bendrofluazide 2.5 mg tabletsper quarter per 1000 prescribing units (age-weighted population)between the intervention district and England as a whole wasmeasured. RESULTS: Comparison of the intervention district with England data demonstratesa median difference of 122.49 PDD before and 206.34 PDD afterguideline production, this change is statistically highly significant(Mann-Whitney two-tailed P < 0.0001; 95% CL = 36.51–104.77).Grouped regression analysis shows no significant difference(0.89) in slope gradients before guideline production (P = 0.35,95% CL = –3.97–5.76), but the difference in slopegradients after (12.95) is statistically highly significant(P < 0.0001; 95% CL = 8.17–17.73). The data suggeststhat the change in clinical behaviour persisted for at leasttwo years. CONCLUSION: Participation of intended recipient general practitioners andlocal specialists in the development of a guideline by an activeeducational method as described was followed by a favourablechange in clinical behaviour which persisted for at least twoyears.

Utilization of Health Services in Physician Offices and Outpatient Clinics by Adolescents and Young Women in the United States: Implications for Improving Access to Reproductive Health Services

PurposeWe examined utilization patterns of adolescents and young women as they seek general and reproductive health services in physician offices and hospital outpatient clinics.MethodsWe analyzed physician office visits in the 2003–2006 National Ambulatory Medical Care Surveys, and hospital outpatient clinic visits in the National Hospital Ambulatory Medical Care Surveys, to examine utilization patterns of females aged 9–26 years by 2-year age intervals and other characteristics such as physician specialty or clinic type.ResultsThe number of visits to primary care physician offices increased with age, from 4.9 million for ages 9–10 years to 9.0 million for ages 25–26 years. The proportion of visits made to obstetrician-gynecologists and family practitioners increased with age, and by ages 15–16 years fewer than half of all visits to primary care providers were made to pediatricians. The proportion of visits to family practitioners increased from 25% at ages 9–10 years to 30% at ages 25–26 years. By ages 17–18 years, a larger proportion of visits were made to obstetrician-gynecologists (33% of 7.0 million visits) and to family practitioners (34%) than to pediatricians (23%). The proportion of visits for reproductive health services peaked at 53% of 7.5 million physician visits at ages 20–21 years. Similar utilization patterns were observed for the 11.0 million hospital outpatient visits to primary care providers.ConclusionsBecause adolescents and young women most commonly utilize healthcare services provided by obstetrician-gynecologists and family practitioners, these specialties should be priority targets for interventions to improve the quality and availability of reproductive health services.     

The impact of the COSHH regulations on workers with occupational asthma

In the UK, the COSHH Regulations give specific guidance thatemployers have duties to inform, instruct and train their employeesabout occupational risks and provide them with suitable healthsurveillance. The aim of the study was to evaluate the impactof the Regulations on employees with occupational asthma. Onehundred consecutive patients attending an occupational lungdisease clinic completed a questionnaire assessing the implementationof the COSHH Regulations in their workplace. Twenty-eight percent had a pre-employment inquiry about asthma, 31% had regularhealth surveillance by questionnaires and 19% had regular lungfunction assessment at work. Pre-employment spirometry was carriedout in 44% of the workers who were exposed to one of the originalseven prescribed agents, significantly more than those who wereexposed to other agents (19%) (p < 0.05). Moreover, figuresfor spirometry during employment were 31% and 8% respectively(p < 0.05). The patients who worked after ‘COSHH’but before ‘MS25’ had a tendency to be providedwith health surveillance more than those who worked after both‘COSHH’ and ‘MS25’. Ninety-one per centof the patients had never been informed about the risks of gettingasthma at work and 73% had never seen the safety data sheets.The workers who (1) worked after ‘COSHH’ introduction;(2) worked in larger firms and (3) were exposed to one of theoriginal seven prescribed agents, had a tendency to be informed,instructed and trained more than the rest. However, there wereonly significant statistical differences (p<0.05) in termsof the safety data sheet provision between the cases who workedbefore the time of the legislation and those employed afterwards.     

A population-based study on use of medications by elderly Brazilians: the Bambuí Health and Aging Study (BHAS)

This study aimed to assess the prevalence and factors associated with use of prescribed and non-prescribed medications among older adults living in Bambuí, Minas Gerais, Brazil. A total of 1,606 (92.2%) out of 1,742 inhabitants aged 60+ years were interviewed. Among the participants, 1,281 (79.7%) and 274 (17.1%) had used prescribed and non-prescribed drugs in the previous 90 days, respectively. Use of prescribed medications was independently associated with gender (female), age (70-79 and > or = 80), higher family income, worse health conditions, and physician visits. Non-prescribed medications were negatively associated with physician visits and positively associated with female gender and consultation with a pharmacist. In general, factors associated with the use of prescribed and non-prescribed drugs in this study were similar to those observed in studies conducted in other countries. Meanwhile, our results differ from those of other studies by showing less frequent use of prescribed medications among the poorer elderly. Moreover, our results suggest that self-medication has been used in place of formal health care in the study community.     

What Do Chaplains Really Do? I. Visitation in the New York Chaplaincy Study

The current study presents findings from the New York Chaplaincy Study about chaplain visits with patients and their families in 13 healthcare institutions in the Greater New York City area during 1994–1996. It documents the distribution of 34,279 clinical visits by religious affiliation, population served (patients, family and friends), and type of healthcare setting (acute care and non-acute care), and analyzes the number and duration of visits with patients by their medical status. Chaplains in acute settings tended to make less frequent but longer visits with patients than chaplains in non-acute settings. On average, chaplains spent less time with patients who were alone than they did during visits with patients whose family was present during the visit or visits with only family members. Average visit duration was positively related to the percentage of visits in each of the 13 facilities that were made in response to referrals (r = .65, p < .05), and the average duration of referred visits was significantly longer (p < .001) than that of non-referred visits (p < .001). The findings are intended to provide a general picture of what these particular chaplains did in these particular institutions over this particular time-period and are not intended to represent a standard of what chaplains should be doing.     

Referrals of patients by family physicians to consultants: a survey of the Israeli Family Practice Research Network

OBJECTIVE: We aimed to analyse factors influencing referral of patients by primary care physicians to specialist consultants at the beginning of the era of direct access to specialists in Israel. METHODS: We carried out a study of referrals by family physicians to specialists over a continuous period of 3 months. Twenty-four certified family physicians filled in a questionnaire detailing referrals during the study period. All patients were referred for consultation to a specialist at regional speciality clinics or hospital out-patient departments. RESULTS: Ten physicians met the study conditions. In 1140 of 10896 (10.5%) visits, patients were referred to specialist consultants. The percentage of referral ranged from 7.4 to 15.9%. The difference between the physicians with the lowest and highest rates of referral was statistically significant (P < 0.0001). The variance in referral rates was not explained by significant differences in physician or practice variables. The types of specialists to whom the most referrals were made were orthopaedic surgeons, ophthalmologists, dermatologists, ear, nose and throat, general surgeons and plastic surgeons. There was a significant correlation between the type of specialist and the age of the patient. Older patients were referred more frequently to urologists, cardiologists and ophthalmologists, while younger patients were referred more frequently to ear, nose and throat specialists and gynaecologists (P < 0.01). CONCLUSIONS: The results of this study can be used as an aid for decision makers in the health services for determining policy. Direct access to some specialties might be appropriate, but not to all. Adoption of a policy based on these findings could lead to reduced health care costs by reducing the burden on hospital emergency rooms. It might also increase patient satisfaction in that the patients will have greater freedom of choice. On the other hand, more appropriate training of family physicians and more extensive self- and peer-quality assurance will increase the primary physician's knowledge and ability to diagnose and treat a broad range of problems and improve the level of care.      

A method for determining patients' perceptions of their health needs.

Success or failure in establishing a meaningful relationship between physician and patient depends to a large extent on how fully the patient communicates, and the physician understands, his/her health needs. Return visits, compliance with the physician's prescribed regimen, and the effectiveness of the treatment and rehabilitation are also closely related to the disclosure and assessment of the patient's health needs. A model of how health needs are determined is presented. Various behavioral outcomes which follow the identification of a health problem and assessment of health needs by a patient are discussed. A Health Needs Assessment Questionnaire is presented in English and Spanish to be used and tested as an aid to the family physician in assessing patient's health needs at the first encounter.     

The Norwegian Mental Health Campaign in 1992. Part II: changes in knowledge and attitudes

A one-Sunday fund-raising TV show in the autumn of 1992 wasbroadcast by the Norwegian Broadcasting Cooperation, one oftwo TV channels covering the whole country. The 6 h TV showconsisted of information on mental health problems and preventioninterspersed with entertainment and reporting fund-raising results.Newspapers, radio and TV had covered the forthcoming TV showextensively. The campaign was evaluated as a nationwide mass-media-basedmental health campaign through a stratified random sample of574 persons. The proportion of the population aware of the factthat suicide takes more lives than traffic accidents increasedfrom 28.2 to 49.3% in men (P<0.001) and from 21.3 to 46.0%in women (P<0.001). Both sexes showed a significant increasein the proportion having an open attitude towards mental illnessin the family. A higher proportion stated they would recommendpeople with a minor mental health problem to consult a generalpractitioner after the campaign than before [from 18.9 to 31.3%in men (P<0.001) and from 21.8 to 34.1% in women (P<0.001)].The Norwegian Mental Health Campaign seems to have succeededin changing knowledge about and attitudes towards mental healthproblems in the general Norwegian population.     

Who in Brazil has a personal doctor?

Background. Continued medical care (including having a personaldoctor) is regarded as an essential aspect of a good healthservice. Objectives. The objectives of the present study were to investigatethe reasons for not having a personal doctor, and the satisfactionwith the care received by patients with and without a personaldoctor. Methods. We conducted a cross-sectional study with data collectedduring 20 days over 6 months in the Emergency Service of theConceição Hospital, the busiest emergency servicein Porto Alegre. The subjects were 553 patients selected throughsystematic random sampling. The main outcome measure was havinga personal doctor. Patients who reported usually to see thesame doctor and remembered their physician's name were regardedas having a personal doctor. Results. Patients who usually use primary care service represented23% of the sample, and were four times more likely to have apersonal doctor (OR = 3.83, CI 95% = 2.41–6.11). Independent,statistically significant variables associated with having apersonal physician were: usually receiving care from a primaryhealth care service (OR = 3.8, CI 95% = 2.39–6.00) andfrom a physician in the private sector (OR = 2.16, CI 95% =1.15–4.00). Patients who had a personal doctor reportedhigher satisfaction with their access to health care. The personaldoctors' specialties were: internal medicine (37%), cardiologist(17%), gynaecologist-obstetrician (13%), family physician (8%)and pneumologist (6%). Conclusions. For patients who attend emergency services in Brazil,primary health care and private medical care provide betteraccess to continuity of patient care. Patients with personaldoctors report higher satisfaction with access to consultations. Keywords. Continued medical care, personal doctor.     

PHYSICIAN KNOWLEDGE OF THE CAGE ALCOHOL SCREENING QUESTIONS AND ITS IMPACT ON PRACTICE

A cross-sectional survey of physicians (n=301) and patients(n=321) at a universitybased department of medicine was completedto determine physician's ability to list CAGE alcohol screeningquestions and how this knowledge is associated with practicepatterns. Forty-five percent of the physicians had heard ofthe CAGE, but only 14% could list all four of the questionscorrectly. Physicians who knew the CAGE were more likely toreport counseling and referral of their patients who abuse alcohol.However, as assessed by patient interview and chart review,patients with an alcohol abuse problem were no more likely tohave been recognized by or to have received more aggressivecare from residents who knew the CAGE than patients cared forby residents who did not know the CAGE. Knowledge of an alcoholscreening test is not sufficient to change physician practicerelated to care of patients with an alcohol abuse problem. Moreattention must be directed towards the development of effectivestrategies which integrate into clinical practice screeningand initial treatment of patients who abuse alcohol.
