Interobserver reliability in physical examination of the cervical spine in patients with headache.

OBJECTIVE: To assess interobserver reliability of two expert headache neurologists when examining the cervical spine of patients with headache. BACKGROUND: The diagnosis of cervicogenic headache involves the physical examination of the cervical spine. METHODS: Twenty-four patients diagnosed as having migraine, tension-type headache, or cervicogenic headache were included in the study. After interview, each patient's cervical spine was examined in a structured way. Reliability was assessed by Cohen's kappa. RESULTS: Reduced range of motion in the cervical spine showed kappa scores indicating moderate agreement. Provocation of headache revealed moderate-to-substantial agreement. Assessment of zygapophyseal joint pressure pain showed slight-to-fair agreement. The kappa values of the circumscribed characteristic tender points showed agreement ranging from "not better than chance" to "substantial agreement." CONCLUSIONS: Our study showed that the interobserver reliability of expert headache neurologists was satisfactory in the majority of the physical examination tests of the cervical spine in patients with different headache syndromes. However, standardization of the clinical tests in order to improve their reliability is recommended.

Can we screen for pelvic organ prolapse without a physical examination in epidemiologic studies?

OBJECTIVE: Large population-based epidemiologic studies of pelvic organ prolapse are rare. One barrier is the need for physical examination in order to confirm disease status. The objectives of this study were to develop a simple screening question for pelvic organ prolapse (POP) and to evaluate its test characteristics in high and low prevalence populations. STUDY DESIGN: Data from 100 women enrolled in the validation study of the Pelvic Floor Distress Inventory (PFDI) were used to identify the question or questions that most accurately identified women with advanced pelvic organ prolapse. After identifying an accurate and reliable screening question from this original group, its test characteristics were evaluated prospectively in 2 additional distinct populations: a group of 120 women presenting to a tertiary care urogynecology clinic (High prior probability of POP) and 448 women presenting to a nurse practitioner for annual gynecologic examination (Low prior probability of POP). Subjects in these 2 groups each completed the screening question and underwent a POPQ examination by a blinded examiner. RESULTS: A single question was identified from the original study population that most accurately and reliably identified those women with POP "Do you usually have a bulge or something falling out that you can see or feel in your vaginal area?" An affirmative answer to this question was 96% sensitive (95%CI 92-100) and 79% specific (95%CI 77-92) for prolapse beyond the hymen. The 1-week test-retest reliability was good (kappa .84). The prevalence of POP in this group was 29%. No other single question or group of questions had better test characteristics. When prospectively evaluated in the second High probability population (prevalence 39%), similar test characteristics were noted: sensitivity 85% (95%CI 71-93), specificity 86% (95%CI 75-92). However, when evaluated in the Low prior probability group (POP prevalence 3.8%) the specificity improved to 99% (95%CI 98-99), while the sensitivity decreased dramatically to 35% (95%CI 15-61). CONCLUSION: Screening for POP without a physical examination is subject to spectrum bias. Spectrum bias occurs when a diagnostic test performs differently in different groups of patients. In groups with a high prior probability of POP, a simple screening question can accurately screen for advanced POP without a physical exam. However, in groups with a low prior probability of POP such as might be seen in a population-based epidemiologic study, this question has poor sensitivity.

Participation in a periodic physical examination program and group health care utilization and costs.

The authors identified 710 male employees of a multinational US corporation eligible to take periodic physical examinations for a consecutive 3-year period (1983 to 1985) and insured by one of the company's health insurers. Group health insurance claims rates and costs for the calendar year 1985 were studied among executives who did not take an examination during the study period, those who took it once or twice, and those who took it all 3 years. Health care utilization for those who did not participate in the program was significantly lower than both groups of participants. Average claim costs in 1985 among those who participated all 3 years ($1,039) was 1.77 times the cost of those who participated one or two times ($588) and 2.30 times the cost of those who did not participate ($452). We conclude that short-term health care utilization and costs are higher among participants than non-participants of a periodic physical examination program.

Direct observation of pain behavior in low back pain patients during physical examination.

Trained observers measured the occurrence of 5 behaviors (guarding, bracing, rubbing, grimacing, and sighing) in a group of 80 low back pain patients undergoing physical examination. Bracing was frequently displayed, rubbing, guarding, and grimacing were moderately frequent and sighing was infrequent. Pain behaviors were much more likely to occur when patients were moving than when they were in a static position. The rate of guarding, bracing, and total pain behavior was predicted by physical examination findings and/or number of prior operations. Patients having longer pain histories were also more likely to show guarded movement. Topics for future research in this area are identified, and the utility of behavioral observation for clinicians is discussed.

On the investigation of men from infertile relations. A clinical study with special regard to anamnesis, physical examination, semen-, hormone- and chromosome analyses, from men with non-"normal" semen.

When investigating men from infertile conjugal relations it is of value early to find variables that give information about the prospects of fertilization, and to know in which patients one needs to analyse serum hormone concentrations and/or chromosomes. A standardized interview and a physical examination were performed prospectively in each case. The findings were compared with the results of a follow-up investigation, with regard to conception rate, performed 3-5 years after the initial investigation. Serum concentrations of FSH, LH, testosterone and prolactin were compared with the results of semen analyses and testicular volume measurements. Mitotic chromosome analyses were performed and the results were compared with the findings in semen. In a selected group of men, extended chromosome analyses--with special regard to the occurrence of induced chromosomal lesions--were performed. The man's age at investigation, sperm density, sperm motility and the duration of the couple's infertility, all gave information about the prospects of conception. A useful score was based on the 'break points' of these four variables, for the estimation of prognosis. Prognostic information was also obtained from total testicular volume and the percentage of morphologically normal spermatozoa (MNS). Men with a long duration of infertility had more frequently azoospermia than the other men. Men with abnormal epididymis(des) had a lower conception rate (CR) than men found normal at physical examination. Otherwise, CR was influenced neither by a positive history of genital disease(s), nor by signs of genital disease(s) at the physical examination. In infertile men with a sperm density of greater than or equal to 20 million spermatozoa/ml and/or a total testicular volume greater than or equal to 30 ml, measurements of FSH, LH and testosterone seem to be of no value. A 'profile' of these hormones, however, does seem to be valuable in men with a sperm density less than 20 million/ml. Prolactin concentration gave no clinically valuable information. Chromosomal aberrations were found in 9.4%. Abnormal karyotypes were absent among men with a sperm density of greater than or equal to 20 million/ml and greater than or equal to 60% MNS. In men with less than 60% MNS there was a significantly increased number of leukocytes with chromosomal lesions.

Senior medical students as patient-preceptors to introduce basic history and physical examination skills to second year medical students.

Senior medical students are used as the patient and the preceptor to introduce the fundamentals of history taking and physical examination to sophomore medical students and this technique compared to the established method for teaching basic skills at the University of Iowa. Senior medical students were equally as effective as staff (residents, fellows, and faculty) in teaching the techniques of history and physical examination and statistically better than staff in providing the sophomore with a) suggestions as to how to improve their technique, and b) how their approach might affect the patient's attitude and behavior.

The predictive value of physical examinations for ascites.

To determine the predictive value of physical signs for ascites, we compared the results of physical examination with those of abdominal sonography in 90 men in hospital with liver disease. The positive predictive values of shifting dullness and prominent fluid waves were low (51% and 73%). We divided the patients into two groups: those with prolonged prothrombin times (72% prevalence of ascites by sonogram), and those with normal prothrombin times (15% prevalence). In patients with prolonged prothrombin times, a prominent fluid wave had a very high positive predictive value for ascites (96%). Many patients with prolonged prothrombin times had ascites despite negative physical signs. In contrast, in those with normal prothrombin times, both shifting dullness and prominent fluid waves were usually falsely positive. Patients with normal prothrombin times and no shifting dullness rarely (2%) had ascites. The predictive value of physical signs for ascites depends on the prevalence of ascites in groups of patients that are examined. The prothrombin time is a useful index for identifying inpatients with a high or low prevalence of ascites and the predictive value of physical signs is enhanced by interpreting them in combination with a patient's prothrombin time.

Dental physical examination.

The objectives of the equine dental physical examination are to detect and quantify oral and dental disorders, to propose and carry out their treatment, and to implement management programs. The veterinarian should be able to offer a prognosis and to detail any future treatment or management plans that may be required. These objectives should take into account the cost of these procedures, and the veterinarian should be prepared to offer a cost-benefit analysis of the problem and the proposed cures.

[The bicentenary of Josef Skoda's birth (1805-1881). An innovator in the field of the physical examination].

The bicentenary of Josef Skoda's birth (December 10(th) 2005) was seen as an excellent opportunity to review his accomplishments for internal medicine. He extended the physical examination, namely percussion and auscultation, and established the scientific basis for these techniques. While Skoda's predecessors interpreted sounds and murmurs by natural philosophy and phenomenologically, Skoda established diagnoses based on empirical and experimental investigations. He compared diagnostic findings with post mortem results at Rokitansky's morgue. Thus, Skoda's work led to the modern capabilities of the physical examination.

Associations between physical examination, laboratory, and radiographic findings and outcome and subsequent racing performance of foals with Rhodococcus equi infection: 115 cases (1984-1992).

OBJECTIVE: To determine whether physical examination, laboratory, or radiographic abnormalities in foals with Rhodococcus equi infection were associated with survival, ability to race at least once after recovery, or, for foals that survived and went on to race, subsequent racing performance. DESIGN: Retrospective study. ANIMALS: 49 Thoroughbreds and 66 Standardbreds admitted to 1 of 6 veterinary teaching hospitals between 1984 and 1992 in which R equi infection was positively diagnosed. PROCEDURE: Results of physical examination, laboratory testing, and thoracic radiography were reviewed. Indices of racing performance were obtained for foals that recovered and eventually raced and compared with values for the US racing population. RESULTS: 83 (72%) foals survived. Foals that did not survive were more likely to have extreme tachycardia (heart rate > 100 beats/min), be in respiratory distress, and have severe radiographic abnormalities on thoracic radiographs at the time of initial examination than were foals that survived. Clinicopathologic abnormalities were not associated with whether foals did or did not survive. Forty-five of the 83 surviving foals (54%) eventually raced at least once, but none of the factors examined was associated with whether foals went on to race. Racing performance of foals that raced as adults was not significantly different from that of the US racing population. CLINICAL IMPLICATIONS: R equi infection in foals is associated with a decreased chance of racing as an adult; however, foals that eventually go on to race perform comparably to the US racing population.

Selective conservatism in abdominal stab wounds: the efficacy of serial physical examination.

An analysis of 186 consecutive patients with anterior abdominal stab wounds in a 2-year period was carried out to assess the efficacy of serial physical examination as the determining factor for the need for laparotomy. Of 106 patients managed by clinical evaluation, the incidence of negative laparotomy was 0.9% and three patients (2.7%) had an "unnecessary" celiotomy. There were no missed injuries or delayed detection of intraperitoneal visceral trauma. The incidence of negative laparotomy among patients subjected to wound exploration +/- peritoneal lavage (n = 41) was 2.4%, and 39 patients had mandatory laparotomy for evisceration, with a negative celiotomy rate of 20.5%. Our experience supports serial physical examination as a highly effective method of "selective conservatism" of anterior abdominal stab wounds. Mandatory laparotomy for evisceration needs further clarification.

The challenge of clinical interviewing and physical examination performance for general practitioners in Turkey.

BACKGROUND AND OBJECTIVES: This study's objective was to better understand the current conditions and style of practice of generalist physicians in Turkey on clinical interviewing and physical examination skills prior to the widespread availability of family medicine postgraduate training. METHODS: This study was performed in 30 primary health centers, randomly chosen from the 110 primary health centers in Izmir, Turkey. We administered a questionnaire to 106 physicians in those centers, asking about their performance during medical encounters. We then observed 166 first-visit encounters of 37 of those physicians. Finally, we compared physicians' reported behavior (as described in the questionnaires) with their actual performance (when observed). RESULTS: In the physician questionnaire, 86.8% of participants agreed that 20 minutes or more was sufficient time for first visits, but in practice, 81.9% of the interviews lasted less than 5 minutes. The major reason cited by physicians for short interview times was overcrowding (72.6%). In 94.6% of the encounters, physicians obtained the history of present illness but the rest of the history, such as past history and family history, was gathered in less than 40% of the interviews. Except for the examination of oral cavity and pharynx, lungs, and heart, almost all the rest of the physical examination was performed in less than 10% of the cases. No written records were kept in 63.0 % of the encounters. CONCLUSIONS: The problems and difficulties present in delivering primary care in Turkey include the physicians' behavior in addition to working conditions.

Physical examinations in inner-city preschools.

This paper describes the physical examination program started in March 1974 and carried out by the Anacostia Headstart Program in Washington DC. Annual totals of 362, 274, and 458 preschool children were examined in 16 schools during the 1973-1974, 1974-1975, and 1975-1976 school years, respectively. For these years, 8, 9, and 12 percent, respectively, had heart murmurs. The rates for abdominal hernias were higher, 11, 17, and 16 percent, respectively. Eczema was also a common problem. Parents had easy access to counseling from health professionals who worked in the program.

A comparative assessment of alignment angle of the knee by radiographic and physical examination methods.

OBJECTIVE: To compare the knee-alignment angle from a full-limb radiograph (mechanical axis) with the anatomic-axis angle as measured by physical examination using a goniometer and by 2 other radiographic methods. METHODS: The knee-alignment angle was measured in 114 knees of 57 subjects who had radiographic osteoarthritis (OA), with a Kellgren/Lawrence grade of >/=1 in at least one knee. The mechanical axis was defined as the angle formed by the intersection of 2 lines, one from the center of the head of the femur to the center of the tibial spines, and a second from the center of the talus to the center of the tibial spines. The anatomic axis was defined as the angle formed by 2 lines, each originating from a point bisecting the femur and tibia and converging at the center of the tibial spine tips. The anatomic-axis angle was measured by 3 methods: 1) physical examination using a goniometer, 2) a posteroanterior (PA) fixed-flexion knee radiograph (anatomic(PA) axis), and 3) an anteroposterior (AP) full-limb radiograph (anatomic(AP) axis). RESULTS: Significant correlations were found between the mechanical-axis angle and the anatomic-axis angle measured by each of the 3 methods: by goniometer (r = 0.70, P < 0.0001), by anatomic(PA) axis (r = 0.75, P < 0.0001), and by anatomic(AP) axis (r = 0.65, P < 0.0001). The anatomic axis was offset a mean 4.21 degrees valgus from the mechanical axis (3.5 degrees in women, 6.4 degrees in men), which was consistent across all methods. CONCLUSION: Knee alignment assessed clinically by goniometer or measured on a knee radiograph is correlated with the angle measured on the more cumbersome and costly full-limb radiograph. These alternative measures have the potential to provide useful information regarding the risk of progression of knee OA when a full-limb radiograph is not available.

The substitution of digital images for dermatologic physical examination.

OBJECTIVE: To investigate the diagnostic accuracy of clinicians viewing a patient's history and static digital image set compared with clinicians who conducted office-based physical examinations of the same patients. DESIGN: Observational study. SETTING AND PATIENTS: One hundred sixteen adult patients presenting with dermatologic symptoms in a university-based practice who consented to have their skin conditions documented with a still digital camera according to a standardized protocol. MAIN OUTCOME MEASURES: Concordance between office-based dermatologists' diagnoses and 2 remote clinicians' diagnoses using still digital images (resolution, 92 dots per inch) and identical medical history data to render diagnoses. RESULTS: When photographic quality was high and office-based clinician certainty was high, remote clinicians were in agreement more than 75% of the time. Office-based and remote clinicians were in agreement 61% to 64% of the time for all cases. No specific disease category appeared to be more or less amenable to diagnosis based on still digital imagery. The diagnostic certainty of the office-based clinician (reported from 0-10) had the most impact on agreement. When cases with office-based clinician certainty of no more than 7 were compared with cases with certainty of at least 9, agreement increased 54% for remote clinician 1 and 111% for remote clinician 2. As an isolated variable, photographic quality had a modest impact on agreement. CONCLUSIONS: Still digital images can substitute for the dermatologic physical examination in up to 83% of cases. This study provides validation of the store-and-forward concept of telemedicine as applied to dermatology. These results serve as the foundation for field testing of the concept in primary care settings.

Surgeon-performed ultrasound in the critical care setting: its use as an extension of the physical examination to detect pleural effusion.

BACKGROUND: Critically ill surgical patients are often difficult to assess for complications because of their altered sensorium, multiple monitoring devices, and immobility. Surgeon-performed ultrasound may enhance the physical examination of these patients and provide for an early detection of select complications. We hypothesized that a focused thoracic ultrasound examination could reliably detect a pleural effusion and the results could be used in the decision matrix for patient care. METHODS: Serial focused thoracic ultrasound examinations were performed by a surgeon and a medical student on critically ill patients. The medical student learned select facets of the physical examination and then demonstrated how ultrasound imaging could enhance these findings. Ultrasound images were recorded on hard copy and videotape, with the results available to the surgical intensive care unit and surgery teams. The images were reviewed and compared with the chest radiograph readings. RESULTS: Forty-seven patients underwent 140 ultrasound examinations. There were 85 true-negative, 46 true-positive, 9 false-negative, and zero false-positive examination results, yielding an 83.6% sensitivity, 100% specificity, and 94% accuracy. Of the 46 true-positive results, thoracentesis was performed or a thoracostomy tube was placed in 5 patients. Nine false-negative ultrasound examinations occurred in six patients, five of whom had their effusions detected on computed tomographic scans. CONCLUSION: A focused thoracic ultrasound examination reliably detects pleural effusions in critically ill patients, and the results can be used successfully in the decision matrix for patient care.
