Observing decision‐making in the general practice consultation: who makes which decisions?

OBJECTIVE: To investigate opportunities for, and types of decision making in the general practice (primary care) consultation, and examine differences in skills of those doctors who are successful at meeting their patients' preferences and those who are less successful. DESIGN: Observation study of doctor-patient consultations in general practice. PARTICIPANTS: Patients attending for routine appointments in 12 general practice surgeries across Oxfordshire. METHODS: A total of 212 doctor-patient consultations were video-recorded. The patients involved completed a questionnaire to elicit their perceptions of how decisions were made. The video-taped recordings were coded with a new instrument, the Evidence Based Patient Choice Instrument (EBPCI), to classify the number and type of decision-making opportunities arising during each consultation. A total of 149 recordings were coded using the Oxbridge Rating Scale to assess the doctors' consultation styles. RESULTS: There was a range of decision-making opportunities in addition to those involving medical treatment. With the exception of 'fitness for work', decisions were generally 'doctor led'. There was only moderate agreement between patient perceptions of their level of involvement in decision making and the objective ratings using the EBPCI. There was wide variation in the ability of doctors to meet their patients' preferences for involvement. CONCLUSIONS: There are many decisions made in primary care consultations, in addition to those about medical treatments, in which patients could be involved to a greater extent than they currently are. Some doctors are significantly better than others at meeting different patients' preferences for their decision-making role. Patients' perceptions of shared decision making appears to be influenced by the doctors' general consultation skills.     

Reversible renal medullary hyperechogenicity in neonatal hypernatremic dehydration

Three exclusively breastfed term neonates were admitted with lethargy, poor feeding, and oligoanuria. All three babies were severely dehydrated and had a weight loss ranging from 18% to 40%. Serum sodium of more than 180 mEq/l and renal failure were observed in all three. Two had very high creatinine levels of 9.5 mg/dl and 6.7 mg/dl. Both these babies also had multiple seizures. One baby required mechanical ventilation. All three babies showed markedly hyperechoic renal medullary pyramids with speckled foci suggestive of crystal deposition that reversed completely on therapy. Urine showed abundant urate crystals in two and an elevated calcium/creatinine ratio of 1.6 in one. There was no evidence of distal renal tubular acidosis, Bartter syndrome, or high serum calcium. Supersaturation of the ions in a markedly hypertonic renal medulla may have led to crystallization, with resolubilization with hydration and restoration of good urine output. The hypernatremic dehydration was primarily due to lactation failure leading to inadequate fluid intake in the face of ongoing insensible losses. High breast milk sodium may have been a contributory factor in one patient.     

Role of coping strategies and attitudes in mediating distress due to hallucinations in schizophrenia

The purpose of the present study was to determine the role of coping strategies and attitudes in predicting distress due to hallucinations in schizophrenia. Seventy-five chronic stable schizophrenia patients were assessed with respect to sociodemographic profile, clinical variables, general psychopathology, phenomenology (severity) of hallucinations, attitude towards hallucinations, distress due to hallucinations (determined by two measures) and coping strategies used to deal with hallucinations. On multiple stepwise regression analysis, 'severity of hallucinations' and 'problem-solving coping strategies' contributed significantly to both measures of distress. It can be concluded that distress due to hallucinations in schizophrenia is determined by severity of hallucinations (stressor) and problem-solving coping strategies. Attitudes do not seem to play any role in this respect.     

Effect of Haloperidol Dacanoate on the Cardiovascular System

Abstract: Rapid speed electrocardiograms were recorded in 13 chronic schizophrenic patients before, and at regular intervals during a six-month trial of haloperidol decanoate. Measurements of conduction intervals in the EEG were carried out blind to patient and to assessment interval. No significant changes in heart rate; PR, QRS on QTc intervals; or T-wave height were found. Neither was there a significant change in the blood pressure. The findings confirm that haloperidol does not have clinically relevant cardiac effects when given in therapeutic doses to physically healthy individuals.
