Pre-operative medical complications in patients admitted to hospital for elective orthopaedic surgery

At the Royal National Orthopaedic Hospital (RNOH) between 1 November 1981 and 31 October 1982 3,628 operations were performed and 96 patients were referred preoperatively to a physician for clinical assessment of their fitness to withstand the operation. In 36 of these patients the operation was postponed because of medical complications and in 6 it was cancelled. The commonest reason for postponement was uncontrolled hypertension (16 patients). It is likely that 24 (67%) of the 36 postponements could have been avoided if arrangements had existed to record the blood pressure, pulse rate, haemoglobin level and urinalysis of each patient at the time of initial hospital attendance.     

FSC Health creates winning formula for freestanding elective surgery centers

Medical specialists are developing free-standing surgery centers with or without the collaboration of local hospitals and health systems. FSC Health has a winning formula and is willing to work with hospitals and health systems as part of plans for a national expansion, but so far the physician-owned entity has expanded independently, writes Ed Egger.     

Health literacy: adverse implications for patients and physicians

An astounding portion of the American adult population lacks a level of literacy to comply with effective delivery of health care. This article outlines the concerns and some measures that practices may adopt to help remedy the problem.     

Doctors' willingness to refer elderly patients for elective surgery

OBJECTIVES: We aimed to examine the relationship between doctors' willingness to refer elderly patients for elective surgical operations and patients' age, comorbidity, institutionalization, living habits and signs of dementia. METHOD: A random selection of 837 medical doctors in Finland (response rate 56%) received a postal questionnaire consisting of 18 vignettes, i.e. imaginary patient cases. Respondents were asked whether they would refer the patient on the vignette for elective surgical operation, treat the patient conservatively, or choose some other alternative. In the vignettes, the age of patients was randomly varied between 65 and 85, at 5-year intervals, to provide eight different questionnaires, and each respondent obtained one of them. RESULTS: The proportion of doctors willing to refer the patients for surgery was inversely related to the patients' age: in all the vignettes, doctors said they would refer fewer patients in the oldest age groups. Almost all the doctors claimed they would refer healthy, home-dwelling persons aged 65-70 years for operations. In the oldest age groups of patients, the doctors' willingness to refer was highest for cataract operations (69%) and hip prosthesis operations (63%), but only 18% of doctors would refer such patients for coronary by-pass operations. Comorbidity and institutionalization were associated with fewer doctors referring the patients: the proportion of doctors willing to refer these patients was about half that of those willing to refer otherwise healthy and home-dwelling patients. Smoking by patients also decreased the proportions of doctors willing to refer, but moderate signs of dementia in an elderly patient with cataract were associated with only a slight decrease in referring. CONCLUSIONS: Doctors are less willing to refer old patients for elective surgery, but comorbidity, patients' lifestyle and institutionalization have a greater effect on referrals than age.      

Measures for patients taking psychotropic drugs who undergo elective surgery

Psychotropic drugs can increase the risk of perioperative complications when given in combination with anaesthesia. Evidence-based guidelines that address this issue are lacking. Consensus-based recommendations were formed for the perioperative management of these patients based on the available literature and a systematic evaluation of perioperative risks by the medical specialists directly involved. Patients who use lithium, monoamine oxidase inhibitors (MAOIs), tricyclic antidepressants or clozapine are at risk of experiencing adverse interactions. The anaesthesiology literature recommends discontinuing irreversible MAOIs and lithium in all cases, and tricyclic antidepressants in patients with systemic disorders. With the exception of lithium, the risks of psychiatric relapse or recurrence associated with discontinuation necessitate intensive integrated psychiatric treatment. Continuation of treatment under strict haemodynamic observation may also be an option in some cases. Patients taking selective serotonin reuptake inhibitors (SSRIs) should be observed carefully for psychological instability and physical abnormalities, and clinicians should be aware of medications that could increase the risk of haemorrhage when used in combination with SSRIs. In these cases, a psychiatrist should be consulted. The same is true for patients taking antipsychotic or other antidepressant medication who develop psychological instability or have a systemic disorder. Given the widespread use ofpsychotropic drugs and the seriousness of the associated risks, it is recommended that the decision whether to continue or discontinue psychotropic medication should become a standard component of preoperative assessment.     

Fasting blood glucose levels in patients presenting for elective surgery

Objective

The incidence of diabetes mellitus (DM) is increasing worldwide; however, its diagnosis is often delayed. Identifying patients with abnormal fasting blood glucose (FBG) levels preoperatively may have important implications for immediate and long-term outcomes. The aim of the present study was to determine the prevalence of impaired fasting glucose (IFG) and provisional diagnosis of DM (PDD) with potential risk factors in patients presenting for elective surgery.

Methods

We measured FBG in consecutive adult patients undergoing elective non-cardiac surgery from September 2006 to August 2007. Patient age, sex, body mass index, and FBG were collected in the morning of their scheduled intervention. FBG was classified according to the World Health Organization categorization. Patients with a history of DM were excluded from the final analysis. The prevalence of IFG and PDD and odds ratio for risk factors were calculated.

Results

Four hundred ninety-three patients without a prior diagnosis of DM were sampled; 19.3% (95 of 493) had IFG and 6.5% (32 of 493) had PDD. Male subjects had a greater risk of PDD than female subjects (odds ratio 2.5, 95% confidence interval 1.2-5.5, P = 0.017). Increased body mass index was not a risk factor for IFG or PDD. The prevalence of IFG but not of PDD had a tendency to increase with age after 40 y.

Conclusion

More than 25% of patients without a prior diagnosis of DM presenting for elective surgery had increased FBG levels. Obtaining this information may initiate not only an earlier detection of DM in some patients but also affect acute perioperative management and outcomes.     

Identification of criteria for the prioritisation of patients for elective general surgery

OBJECTIVE: A single visual analogue scale is used in New Zealand to prioritise patients for elective general surgery. Although it reflects clinical judgement, it has been criticised for its lack of transparency. We wished to elicit generic criteria used by surgeons for prioritisation of patients for elective general surgery in order to improve the transparency of the visual analogue scale. METHODS: Semi-structured interviews were undertaken with 15 general surgeons. Using the repertory grid method, surgeons were asked to explain their rationale for distinguishing between patients they considered a high, medium or low priority for treatment. Interviews were audiotaped, transcribed and analysed for themes. The accuracy of the thematic analysis was checked using a five-point Likert scale to assess surgeons' agreement with the identified themes. Further testing to check for face, content and construct validity was undertaken with a purposive sample of six surgeons prioritising patient vignettes. RESULTS: Eight major themes were deduced: diagnosis; treatment; patient characteristics; symptomatology and sequelae to date; future complications; quality of life; psychological/emotional impact; and socio-political/logistic factors. The utilisation of these themes by surgeons was confirmed. Tests of collinearity indicated good content validity. Factor analysis confirmed the hypothesis of one underlying construct, namely priority. CONCLUSION: Seven of the themes became the basis for a new clinical priority assessment criteria tool using visual analogue scales to determine priority of patients for elective general surgery. Further testing of reliability and validity is needed.     

Judgment analysis of surgeons' prioritization of patients for elective general surgery.

BACKGROUND: Access to elective general surgery in New Zealand is governed by clinicians' judgment of priority using a visual analog scale (VAS). This has been criticized as lacking reliability and transparency. Our objective was to describe this judgment in terms of previously elicited cues. METHODS: We asked 60 general surgeons in New Zealand to assess patient vignettes using 8 VAS scales to determine priority. They then conducted judgment analysis to determine agreement between surgeons. Cluster analysis was performed to identify groups of surgeons who used different cues. Multiple regression for the combined surgeons was undertaken to determine the predictability of the 8-scale VAS. RESULTS: Agreement between surgeons was poor (ra=0.48). The cause of poor agreement was mostly due to poor consensus (G) between surgeons in how they weighted criteria. Using cluster analysis, we classified the surgeons into 2 groups: 1 took more account of quality of life and diagnosis, whereas the other group placed more weight on the influence of treatment. The 8-scale VAS showed good predictability in assigning a priority score (R2=0.66). DISCUSSION: The level of agreement reflects surgeons' practice variation. This is exemplified by 2 distinct surgeon groups that differ in how criteria were weighted.

Findings and implications from preadmission screening of elderly patients waiting for elective surgery

Volunteers trained by a social worker did a telephone screening of 716 elderly persons waiting for elective surgery to determine in advance of admission their need for social services. On the basis of their findings patients were given a risk rating by a social worker. While the survey was experienced positively by patients, volunteers, and social workers, the results do not establish its value in terms of shortened length of stay. Aging females living alone required the greatest amount of social work and had the longest length of stay. This group requires further study, along with the connection between intensity of illness with social problem vulnerability. The study raises other important questions critical to programming for an increasingly older population.     

Health literacy: implications for family medicine

As many as 90 million Americans have difficulty understanding and acting on health information. This health literacy epidemic is increasingly recognized as a problem that influences health care quality and cost. Yet many physicians do not recognize the problem or lack the skills and confidence to approach the subject with patients. In this issue of Family Medicine, several articles address health literacy in family medicine. Wallace and Lennon examined the readability of American Academy of Family Physicians patient education materials available via the Internet. They found that three of four handouts were written above the average reading level of American adults. Rosenthal and colleagues surveyed residents and found they lacked the confidence to screen and counsel adults about literacy. They used a Reach Out and Read program with accompanying resident education sessions to provide a practical and effective means for incorporating literacy assessment and counseling into primary care. Chew and colleagues presented an alternative to existing health literacy screening tests by asking three questions to detect inadequate health literacy. Likewise, Shea and colleagues reviewed the prospect of shortening the Rapid Estimate of Adult Literacy in Medicine (REALM), a commonly used health literacy screening tool. Both the Chew and Shea articles highlight the need for improved methods for recognizing literacy problems in the clinical setting. Further research is required to identify effective interventions that will strengthen the skills and coping strategies of both patients and providers and also prevent and limit poor reading and numeracy ability in the next generation.     

Nutritional status of elective gastrointestinal surgery patients pre- and post-operatively

BACKGROUND AND AIMS: Studies have indicated that undernutrition is common on admission to hospital but there is limited data on change in nutritional parameters during the hospital stay. We assessed the nutritional status of elective gastrointestinal surgery patients on admission and documented change in nutritional indices during hospitalisation. METHODS: Two hundred patients aged 18-80 years undergoing elective open gastrointestinal surgery were nutritionally assessed on admission and 150 were reassessed on commencement of oral diet post-surgery. Data were collected on height, weight, upper arm anthropometry and hand-grip dynamometry. RESULTS: On admission BMI <20, 20-24.9 and >25, respectively, were found in 9%, 34% and 57% of patients. Post-surgery, 34% of patients experienced a clinically significant weight loss. Males lost significantly more weight (3.7% vs 1.6%, P<0.001) and tended to lose muscle mass while females preferentially lost subcutaneous fat. CONCLUSIONS: The incidence of undernutrition on admission appears to be lower than previously reported. However, clinically significant weight loss was common and this study highlighted gender differences in the changes in nutritional parameters experienced by gastrointestinal surgery patients. This differential influence of gender warrants further investigation and may have implications for the nutritional management of such patients.     

Health literacy in Suriname

Background: Low health literacy is an independent predictor of cardiovascular mortality. However, data on health literacy in low- and middle-income countries are scarce. Therefore, we assessed the level of health literacy in Suriname, a middle-income country with a high cardiovascular mortality.

Methods: We estimated health literacy in a convenience sample at an urban outpatient center in the capital and at a semirural health center, using the validated Rapid Estimate of Adult Literacy in Medicine adapted for the Dutch language (REALM-D) instrument. REALM-D scores vary from 0 to 66 (all correct). The primary outcome was the level of health literacy. Furthermore, we assessed the effect of age, sex, ethnicity, disease history, research location, and level of education on health literacy with multivariable linear regression.

Results: We included 99 volunteers (52% men; 51% urban research location) with a mean age of 44.9 years (SD 13.4). The mean REALM-D score was moderate: 48.6 (SD 8.1). Greater health literacy was associated with male sex, an urban research location, and a higher educational level.

Conclusion: Health literacy was moderate in these Surinamese participants. Health care workers should take health literacy into account, and targeted interventions should be developed to improve health literacy in Suriname.
