McKinstry and Wang Aim
To investigate doctors’ clothing as a form of non-verbal communication.
McKinstry and Wang Procedure
- 475 patients from five general medical centres in Scotland participated.
- There were 8 images of a female or a male doctor each dressed different but in a similar pose.
- They were asked which they would feel happiest seeing for the first time (0-5 scale) , whether they have more confidence in one of the doctors, whether they would be unhappy with any, which looked most like their own.
- Finally, they were asked closed questions about doctors’ dress.
McKinstry and Wang Results
- The male doctor wearing a suit and tie or the female in a white lab coat was preferred.
- Older patients and those in a higher social class preferred traditionally dressed doctors.
- 64% said the way their doctor dressed was very important.
- 28% ppts said they would be unhappy seeing one of the doctors (informal).
- The female doctor overall received higher ratings.
- 41% said they had more confidence in the formally dressed doctors ability, suggesting the way a practitioner dresses matters to their performance.
- They also said their doctor looked most like the smartly dressed one.
McKinlay Aim
Verbal communications: Investigated understanding of maternity words used by practitioners in a maternity hospital
McKinlay Procedure
- 87 females using a maternity service.
- Split into those who used maternity services regularly (Utilisers) and those who didn’t (Underutilisers).
- The 13 words chosen were words that some but not all doctors would use as they represented a grey area of verbal communication e.g. enamel, mucus.
- Participants were read the word, heard it in a sentence and were asked to say what it meant.
- Responses recorded were verbatim and were scored independently by two doctors: they were blind - unaware of ppts and the other doctor’s score.
- One year later, doctors on the ward had to indicate the level of understanding they would expect from the patients.
- The inter-rater reliability was high, generally giving the same ratings.
McKinlay Results
- Those who underused the service were less likely to understand the words compared to regular users, who only struggled with navel and rhesus.
- Women had far better understanding than doctors anticipated. The comprehension for the word ‘purgative’ however was lower than anticipated.
- Women who already had at least one child were slightly more likely to comprehend words than those attending the hospital in their first pregnancy
Verbal Communication: Ley Aim
Investigated the frequency of patients forgetting verbal advice given by their doctors.
Ley Procedure
This was investigated by asking patients who had just seen a doctor what their practitioner had told them to do. This was then compared with a tape recording of what had actually been said.
Ley Results
- Patients remembered 55% of what was said, they remembered the first thing told, things that were categories, and that they remembered more if they had medical knowledge.
- This means that things such as order, perceived importance and nature of information, patients age, anxiety level and medical knowledge influenced forgetfulness.
- Ley suggested practitioners should state the key information first, giving concrete-specific advice which is categorised and repeat key points.
Byrne and Long Procedure
Analysed 2500 medical consultations from a range of countries to investigate style. They found that doctors consistently used either a patient-centred or a doctor-centred style.
Byrne and Long Findings
- They found seven different consultation styles ranging from extremely doctor-centred to extremely patient-centred.
- Doctor centred: asked questions that required only brief answers e.g. yes or no; focused mainly on the first problem mentioned; ignored attempts to discuss other problems; controlling; directing; termination.
- Patient centred: open-ended questions e.g. Can you describe the situation when the pain occurs; avoided medical jargon; allowed the participant to participate in decision making; advising; reassuring; seeking patient ideas.
Practitioner Style: Savage and Armstrong
Compared consultation satisfaction between patient-centred versus doctor-centred practitioner styles.
Savage and Armstrong Procedure
200 patients consented to have their consultation recorded and were randomly allocated to either condition. They used two questionnaires to measure satisfaction.
Savage and Armstrong Findings
Overall a high level of satisfaction was found, but it was higher for the directed (doctor-centred) group who were more satisfied with the explanation and with their own understanding.
Type I error
Type I: The patient is not ill, but is diagnosed with an illness (False positive).
Type II error
Type II: Patient is ill, but is not diagnosed with illness (false negative)
Disclosure of Information (Robinson and West) Aim
- If a patient does not disclose all their symptoms or is not honest, it will increase the likelihood of a type one or type two error.
- Robinson and West investigated the difference and effectiveness between a computer questionnaire and a paper questionnaire in eliciting medical histories from patients.
Robinson and West Procedure
- Participants were 69 patients of a GU clinic in Northern England randomly allocated.
- Patients completed either computer questionnaire or paper then had a consultation with a doctor in which notes were made. Comparisons were made between:
Number of symptoms reported
Number of previous attendances at GU clinic
Number of sexual partners in the last 12 weeks
Robinson and West Findings
- Computer and paper questionnaires yielded more symptoms than consultation
- Mean no. of sexual partners was greater in the computer condition than the paper and the doctor notes.
- This suggests that computers can be used to help patients communicate more comfortably and openly.
Delay in seeking treatment (Safer)
Investigated what factors influence patients to delay seeking treatment for a new symptom.
Safer Procedure
- 93 patients presenting a new symptom were interviewed about their health behaviours leading up to their current illness.
- Questions were: “What was your very first symptom?” and “When did you decide to see a doctor?”. They were scored on a 9-point scale
Safer: what three stages to delay?
Appraisal, illness, utilisation
Appraisal delay
number of days elapsed from first noticing symptom up to the day they concluded they were ill
Illness delay
number of days from the end of appraisal delay to the day they decide to seek professional help
Utilisation delay
the final stage: end of illness delay to time of when they were seen in clinic
What predicts length of delay?
the , severity and location of symptoms, the perceived importance of symptoms, awareness that you cannot treat the illness yourself, obstacles to receiving care can all delay treatment.
Safer conclusions
Safer et al. concluded a variety of factors (perceptual, situational, appraisal) delay seeking medical treatment. Safer stated that delays come from a failure to appraise the situation adequately.
Hypochondriasis
persistent fear of having a serious medical illness. They interpret normal sensations, minor symptoms and bodily functions as a sign of an illness with a negative outcome. For example, a person with hypochondriasis may fear that a bruise is a sign of a serious disease.
Barlow and Durand
- Barlow and Durand conducted a case study into Gail, a married 21-year-old female.
- Minor symptoms e.g. headache resulted in extreme anxiety.
- She avoided exercise, laughing and noted anything that could be a symptom.
- Doctors repeatedly reassured her nothing was wrong, so she ended up avoiding going to see any more doctors.
Munchausen Syndrome
Factitious disorder characterised by physical or psychological symptoms that are intentionally produced or faked to assume the sick role, be the centre of attention and be cared for. People intentionally produce or pretend to have physical or psychological symptoms of illness.
Aleem and Ajarim
- Reported on the case of a 22-year-old woman who attended their hospital in Saudi Arabia with swelling on her body. She had been seen on numerous occasions in the hospital since she was 17 and given various treatments, such as antibiotics and surgical drainage.
- Suspicions were raised by the hospital when it was felt that the ailments she had did not appear to have a physical cause.
- Upon admittance to the psychiatric ward the nursing staff eventually found a needle with faecal material in it in her bed. The patient left the hospital when confronted after becoming very angry and did not return again.
Types of non-adherence include:
- Failure to follow treatment (e.g. to take tablets every 12 hours)
- Not engaging in preventative measures linked to health (e.g. stopping smoking)
- Failing to attend further appointments or interviews
Problems caused by non-adherence include:
- Wasted money on drugs
- Worsening of health
- Financial costs when appointments are not kept and they are unavailable for others to take
Rational non-adherence (Bulpitt)
Rational non-adherence refers to the patient making a reasoned decision due to undertaking a cost-benefit analysis. This means that a reason for non-adherence could be as a result of a well-considered and reasoned thought process that leads the patient to believe non-adherence is more beneficial.
Bulpitt Study
Bulpitt looked at the risks and benefits of a drug treatment for hypertension (high blood pressure).
Risks included increased diabetes, gout, and dry mouth but these were either not serious or at a very low rate.
Benefits included reduction in strokes by 40% and coronary events by 44%.
Bulpitt concluded that the benefits from treating hypertension in elderly patients far outweigh the disadvantages. It seems people rationally decide not to take the medication because of the risks whilst ignoring the benefits.
The Health Belief Model (Becker and Rosenstock)
The model outlines the factors that explain the beliefs and consequent decisions people make about their health. It assumes that the likelihood that individuals will follow medical advice depends directly on two assessments that they make: Evaluating the threat and a Cost-Benefit Analysis.
First belief of The Health Belief Model
The first stage is the evaluation of the health threat which includes:
- the perceived seriousness (the more serious, the more likely adherence)
- the perceived susceptibility (the more vulnerable, the more likely adherence) and cues to action.
Demographic factors e.g. age, socio-psychological variables and cues to action are all modifying factors that influence the perception of the problem. For example, an obese person may be in danger of developing a heart condition, however since they are young they believe they are less susceptible reducing the risk to minor.
Second belief of The Health Belief Model
A cost-benefit analysis influences the likelihood of taking action. For example, comparing the perceived benefits (being healthier) against the perceived costs (financial, situational, social). All these factors as well as cues to action interact to predict the likelihood of taking preventative health actions.
Self-reports to measure non-adherence
Self-reports involve asking the patient if they adhere to treatment requests. These are subjective and susceptible to response bias.
Subjective: self-reports (Riekart and Droter) Aim
Looked at the implications of non-participation in studies using self-report measures to investigate adherence to medical treatment for adolescents with diabetes.
Riekart and Droter procedure
- Adolescents with diabetes for more than one year (total of 94 families).
- The adolescents completed a series of questionnaires and interviews while their parents also completed a questionnaire.
- They both had a questionnaire to complete at home with a self-addressed return envelope - if not done within 10 days, they were called to remind them.
- Families were divided into three groups: participants/returners (52), non-returners (28) and non-consenters (14).
Riekart and Droter findings
- Significant differences in adherence levels between participants and non-returners.
- Those who returned the questionnaire had higher adherence scores and tested blood sugar more frequently.
- This suggests that when self-report measures are used the results may be distorted if only the results of those that completed the self-report are considered.
Objective: pill counting (Chung and Naya) Aim
To investigate if you can electronically assess adherence to oral asthma medication by using a trackcap.
Chung and Naya procedure
- 57 with asthma patients
- Underwent a screening period of three weeks and a 12 week treatment period in which they were told to take their medication twice a day, one in the morning and one in the evening approximately 12 hours apart and not at mealtimes.
- They received a three week supply with a week to spare.
- They were dispensed from a bottle fitter with a TrackCap medication monitoring system that registers when the bottle is opened/closed.
- Participants returned every three weeks to have their tablet counts measured.
Chung and Naya findings
- On days when patients took exactly 2 tablets, the mean time between doses 12½ hours.
- Median 89% compliance was found from Trackcap, but Median 92% from tablet counts. - Concluded that it is possible to electronically assess adherence with an oral medication using an event monitoring system.
- Compliance was measured by the number of times the cap was opened, the number of days the cap was opened 8 hours apart and number of pills left at the 12 week period.
Biochemical tests (Roth and Caron)
Roth and Caron suggested non-adherence could be measured through blood and urine samples.
Roth and Caron procedure
- They conducted a study with 116 patients whose antacid regime was monitored.
- Patients estimated their intake average 89%, however actual intake averaged 47%.
- They found that pill counting was inaccurate and that patient self-reports often overestimated when they said they took medicine regularly.
Roth and Caron Conclusions
Therefore, Roth and Caron concluded the best measure of non-adherence is objective, quantitative tests, such as biochemical tests to measure non-adherence. They suggested that urine and blood tests taken over a number of months will give a more accurate indication of adherence.
Repeat Prescriptions (Sherman et al.)
Investigated if prescription refill history identified poor adherence with asthma medications more frequently than the doctor’s assessment.
Sherman et al. Procedure
- 116 children with asthma were interviewed with their parents on a clinic visit.
- Adherence was checked by telephoning the patient’s pharmacy to assess the ‘refill rate’.
- It was assumed that if the medication (the ‘refill’) was not collected from the pharmacy, then it could not have been taken, whereas if it was collected then the original prescription must have been taken.
- Patient adherence was operationalised by calculating the number of doses refilled divided by the number of doses prescribed over a period of up to 365 days.
Sherman et al. findings
Adherence was 72%, 61% and 38% for the three different inhalers prescribed to the children.
Checking refills is an accurate way of measuring adherence. Also found doctors are not able to tell if a patient is using their inhaler from consultation alone.
Improve Practitioner Style: Ley
Improve practitioner style by changing information presentation techniques. Ley Prepared a booklet of guidelines for doctors on how to communicate more clearly with patients.
Satisfaction: including listening to the patient and finding out what their worries are, etc
Understanding and memory: avoiding jargon, encouraging feedback to increase recall of instructions, etc
C:selecting Content - being aware of the effect of what they say to the patient (e.g. will it cause fear, is the patient particularly vulnerable), etc.
Use simple language, state the key information first, repeat key points (by summarising).
